Abstract
The utility model provides a kind of a kind of spinneret of petal-shaped abnormity hollow core staple fibers in synthetic fibers shaped device field, including plate body, there are some spinneret orifices in array distribution on the plate body, the spinneret orifice includes the introduction segment of entrance location and the capillary section of outlet port, introduction segment corresponds with capillary section to be connected, the introduction segment is circular hole, and capillary section center is provided with deflection cone, and deflection cone periphery is provided with some petal holes.The petal-shaped abnormity hollow core staple fibers spinned using the utility model spinneret, not only there is preferable warmth retention property, refractivity, crimpiness and bulkiness, but also have the advantages that degree of hollowness is high, specific surface area is big, moisture absorbing and sweat releasing, it is ventilative it is comfortable, feel is smooth, product can be used for inserts and spinning.
Description
Technical field
It the utility model is related to a kind of spinneret for producing fiber, more particularly to a kind of special-shaped hollow rejuvenation polyester staple fibers
The spinneret of Wesy, belong to synthetic fibers field shaping technique.
Background technology
Polyester high polymer molten is mainly passed through C-shaped or double arcuate slots by the spinneret of recycled polyester hollow core staple fibers
Die capillaries be transformed into the thread of rounded hollow sections shape, be then processed into hollow core staple fibers by cooled and solidified again.
The spinneret of existing spinning recycled polyester hollow core staple fibers is generally in the majority with the circular spinneret orifice of design, and generally use is such
Not only rigidity is big for the circle hollow core staple fibers of spinneret spinning, and soft resilience is poor, and glossiness and moisture absorbing and sweat releasing effect are not
Good, product can typically be only used to inserts.
Utility model content
The purpose of this utility model is to provide a kind of spinneret of petal-shaped abnormity hollow core staple fibers, the fibre for producing it
Dimension resilience is high, specific surface area is big, hygroscopicity rate is high.
Therefore, the technical solution that the utility model uses is：A kind of spinneret of petal-shaped abnormity hollow core staple fibers
Plate, including plate body, have some spinneret orifices in array distribution on the plate body, the spinneret orifice include entrance location introduction segment and
The capillary section of outlet port, introduction segment corresponds with capillary section to be connected, and the introduction segment is circular hole, and capillary section center is provided with and led
Flow cone, deflection cone periphery are provided with some petal holes.
The design that the device passes through spinneret orifice so that from capillary section extrusion after fiber cross-sectional be in hollow petal shape,
Petal surface carries multiple grooves, the recycled polyester hollow core staple fibers spinned using the utility model spinneret, and resilience is good, ratio
Surface area is big, moisture absorbing and sweat releasing, feel are smooth, and has preferable warmth retention property, refractivity, crimpiness and bulkiness, and product was both
It can be used as filler, can be used for spun yarn again.
As utility model further improvement is that the petal hole is at least evenly equipped with four in deflection cone periphery.
Further, it is connected between the deflection cone and plate body through dowel, the dowel is by adjacent petal hole phase
Isolation.
To ensure that wire vent is smooth, the introduction segment be the circular hole with interior chamfering, introduction segment and capillary section link position from
It is upper first to gradually taper up downwards, then gradually amplification, deflection cone is in up-small and down-big taper type.
It is that the deflection cone lower end radii is 0.25 ~ 0.5mm, described as further improve of the present utility model
The overall radius of mouth is 0.75 ~ 1.25mm under petal hole, and the minimum widith of dowel is 0.02mm.The spinneret of the structure is fitted
For producing regenerative polyester staple fiber.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model spinneret.
Fig. 2 is the longitudinal profile structure schematic of spinneret orifice.
Fig. 3 is Fig. 2 A to structural representation.
In figure：1 plate body, 2 entrance holes, 3 capillary sections, 4 deflection cones, 5 petal holes, 6 dowels.
Embodiment
As Figure 1-3, it is a kind of spinneret of petal-shaped abnormity hollow core staple fibers, is in array distribution on its plate body 1
There are some spinneret orifices, spinneret orifice includes the introduction segment 2 of entrance location and the capillary section 3 of outlet port, introduction segment 2 and capillary section 3
Correspond and be connected, introduction segment 2 is circular hole, and the center of capillary section 3 is provided with deflection cone 4, and the periphery of deflection cone 4 is provided with some petal holes
5, introduction segment 2 is the circular hole with interior chamfering, and introduction segment 2 first gradually tapers up from the top down with the link position of capillary section 3, then gradually
Amplification, deflection cone 4 is in up-small and down-big taper type；Petal hole 5 is evenly equipped with four or six in the periphery of deflection cone 4
It is individual, eight etc., be connected between deflection cone 4 and plate body 1 through dowel 6, adjacent petal hole 5 is isolated by dowel 6.
For convenience of the production of Regenerated Polyester Fibres is carried out, the lower end radii of deflection cone 4 is R1=0.25 ~ 0.5mm, petal hole 5
The overall radius of lower mouth is R2=0.75 ~ 1.25mm, and the minimum widith of dowel 6 is 0.02mm.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can is special to some of which technology
Sign makes some and replaces and deform, and these are replaced and deformed in the scope of protection of the utility model.
